BLOWER FOR, THRESHING-NLACHINES AND THE LIKE.

Application filed December 6, 1919.

To all whom it may concern:

Be it known that I, VVILFRID OUnLLET'rn, a subject of the King of Great Britain, residing at St. Scholastique, Province of Quebec, Canada, have invented certain new and useful Improvements in Blowers for T hreshing- Machines and the like; and I do hereby dcclare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention has relation to blowem for threshing machines and the like, and the principal object thereof resides in the provision of means for, in con unct1on with the ordinary fanning attachment of a threshing machine, imparting a greater degree of separation of the straw and chaff from the grain.

Another object of the invention is to provide an attachment for threshing machines that both removes the straw and chaff and blows or stacks the same at a distance from the machine.

With the above and other objects in view which will hereinafter appear as the description continues, the invention consists of the novel features of construction, combination and formation of parts as will be hereinafter more fully described and particularly pointed out in the appended claim.

In the accompanying drawings has been shown a simple and preferred form of the invention, it being however, understood that no limitation is necessarily made to the precise structural details herein exhibited, but the right is hereby reserved to any changes, alterations or modifications to which recourse may be had that come within the scope of the claim without departing from the spirit of the invention or sacrificing the efficiency of the same.

In the accomponying drawings:

Figure 1 is a side elevation of the invention;

Fig. 2 is an end elevation of the same;

Fig. 3 is a vertical section;

Fig. 4 an opposite end elevation; and,

Fig. 5 is an elevation with parts in section of the wheel casing and drive shaft.

Referring more particularly to the accompanying drawings wherein like and corre- Specification of Letters Patent.

Serial No. 343,034.

sponding parts are designated by similar reference characters throughout the several vlews:

The apparatus herein shown, comprises a base 1, vertical uprights 2, horizontal bars 3, and the angularly disposed bars 41-. A drum or casing 5, preferably constructed of sheet iron, is supported upon said base by the aforesaid uprights and beams 2, 3 and 4, and said casing 5 is provided with an ex tension 6, the outer walls 7 of which form an entrance opening or chute for the introduction of straw or chaff from the regular blower of the threshing machine.

A shaft 8 has bearings in one of the bars 3 and the platform 9 of the casing and extends through the latter, carrying a pulley 10 and a blower wheel 11, comprising the blades 12.

The extension 6 is provided at its side portions with doors 13 and 14, which when opened allow for the passage of the straw and residue from the threshing machine to the auxiliary blower. Either of the doors may be opened at each side of the apparatus for connection with the outlet opening of the threshing machine and a suitable means may be provided for holding said .doors against movement when adjusted.

In operation, the straw and residue from the threshing machine passes through one of the doors 13 or 14, and into the extension 6 and the same is sucked into the blower proper,,by the blower wheel 11 and by the cooperation with the ordinary blower of the threshing machine, the straw is blown clear of the latter, to form a stack.

A belt may be trained around pulley 10 or the above recited mechanism can be directly connected to the threshing machine operating mechanism.

It is obvious that the straw and residue will be blown a further distance from the threshing machine, by the use of the present device, than has hitherto been accomplished with the ordinary machines.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

The combination in a device such as described, of a frame includin upright and inclined bars, and horizontal bars connected V thereto; an angular housing mounted in one carried by the said shaft, said circular h0us-. ing having an outlet at its gupper side,

said housings having a communicating 0 ening therebetween,- and. a. c1osuresecure toone sideof the angular housing as and for the purposes set forth. 7 7 r In Witness wherecf have hereunto set my hand.
